12.3.5 Operator Messaging Address Enable Packet
The contents of this section apply to the FLEX™ Roaming Decoder. They are not applicable to
the FLEX™ Non-Roaming Decoder.
The operator messaging address enable packet is used to enable and disable the built-in FLEX
operator messaging addresses. Enabling and disabling operator messaging addresses does not
affect what frames the decoder IC decodes. To decode the proper frames, the host must modify the
FF bits in the Control Packet or the AF bits in the Frame Assignment Packets. The ID of the
operator messaging address enable packet is 4.

OAE: Operator messaging Address Enable. When a bit is set, the corresponding operator
messaging address is enabled. When it is cleared, the corresponding operator messaging address is
disabled. OAE₀ through OAE₁₅ corresponds to the hexadecimal operator messaging address values
of 1F7810 through 1F781F respectively. (value after reset=0)
12.3.6 Roaming Control Packet
The contents of this section apply to the FLEX™ Roaming Decoder. They are not applicable to
the FLEX™ Non-Roaming Decoder.
The roaming control packet controls the features of the FLEX decoder that allow implementation
of a roaming device. The ID of the roaming control packet is 5.
